The forward end of the easing 22 receives a disc shaped front wall piece 23, which may be secured in the forward end of the casing 22 by means ofscrews 24 or the like, which may be suitably arranged upon the casing to preventtheir removal when the lock has been assembled. The improved combination'loclr A furthermore includes a shaft portion 30 arranged axially within the housing 22, with an end lthereof `projecting outwardly of the dial piece 20, this shaft portion 30 providing a passageway 31 therethrough within which the ignition switch stem 32 is longitudinally slidable, for purposes which will be Subsc-- quently setr forth.

This shaft portion 30 is rotatably mounted in the position above described, and to this end a supporting member 34 is arranged within the housing 22, including a disc `shaped body portion 35a, and the forwardly extending annular flange 35 which has a recess 36 therein from the outer periphery thereof, adapted to receive la retaining pin 37 which is carried in radial inwardly projecting relation by the housing 22, substantially as is illustrated in Figure 1 of they drawings. The supporting member 34 iixedly recei'ves in the axial opening provided therethrough, a tubular member 38 which is rigid with the supporting member 34, and within which tubular support member 38 the stem or shaft 30 is rotatably mounted in the position above mentioned.

The lock shaft 30 projects through the supporting member 34, and at the forward yend thereof detachablyl supports a radially extending pin 40, which operates within a recess 41 provided forwardly of the body lportion 35 of the retainingmember 34, in-

wardly of the periphery of the annular flange 35 thereof. Upon rotation of the shaft 30 the pin 40 is free to rotate in this space or compartment 41. The shaft 30 at the rear end thereof preferably provides a flat surface 44 and on which end of the shaft 30, outwardly of the dial flange 20 the hand operating member 46 may be mounted, which may be of any conventional character, and which radially supports thereon a screw 47 adapted to set against the flat surface 44 of the shaft 30,

vso that upon rotation of the hand operating member 46, the shaft 30 may be rotated or moved to operate the tumblers of the lock mechanism A, as will subsequently appear. It may be stated that the member 46 also includes the dial 50 which is provided with graduations 55 thereon adapted to be aligned with an indicator mark 56a which is carried by the dial fiange 20 in order to arrive at the proper combination for setting the tumblers.

Referring to the arrangement of tumblers, inner, intermediate, and outer tumblers 56, 57 and 58 are preferably provided, relatively movable, and concentrieally supported about the shaft 30. The tumbler 56 is supported directly upon the tubular support 38 above described, whereas the intermediate tumbler 57 is spaced from the tumbler 56 by means of a spacing sleeve or cylinder 59, and the intermediate and outer tumblers 57 and 58 are separated by means of a spacing cylinder 60. These spacing cylinders 59 and 60 at their forward ends are sweated within suitable grooves provided in the rear face of the supportingpiece 34, the annular grooves being more particularly illustrated at 65 in Fig. 9 of the drawings.

The tumblers 56, 57 and 58 are of novel formation, and the tumbler 56 has been illustrated in detail in figure 10 of the drawings. Inwardly from the forward edges of these tumblers 56, 57 Vand 58, a. slot 71 is provided whichextends for the major length of the tumblers, and it is the object in operating the lock to align the slots 71 of these tumblers with respect to each other, and also with respect to a similar slot 72 which is provided. longitudinally in the supporting tuby the shaft 30 may be moved rearwardly.

through these aligning slots, in order that the stem 32 may be longitudinally moved for the purpose of operating such mechanism as a transmission lock controlling bolt, or the like. 56 is preferably provided with a rearwardly extending segment 78, as lare also the tumblers 57 and 58 provided with similar rearwardly extending segments 79 and 80. The segment 79 is much wider than the segment 78, as is also the segment 80 much wider than the segment 79; the segment 80, in fact, extending almost the entire circumference about the rear end of the tumbler 58, as is illustrated in Fig. 8 of the drawings, where these segments are illustrated in relation to each other.

As an operating means for the tumblers, a control washer 90 may be provided, which is illustrated in detail in Fig. 4 of the drawings, and which is provided with acentral opening 91 therethrough to receive the shaft 30 therethrough. It must be noted that the control washer 90 is provided with a key 92 extending radially into the opening 91 which projects into a slot 94 provided longitudinally in the shaft 30. The washer 90 is clamped between the rear edge of the tubular supporting member'38 and the dial flange 20, and it will of course rotate upon rotation of the At the rear end thereof the tumbler:

- Similarly the slow :speed rband 'is provided withwav shaft fwhich has aV spiral spring 131l thereabout,under compression,jengaging the supporting Vblock 132 j one end thereof, and the band lug at the opposite end thereof, the functions of these springs being that of inaiiit'ainingthe bands loose so `that upon operation of the reverse orA slow speed pedals they may be respectively tightened`as can be readilyfunderstood by anyits,

onefslrilled inthe art to which this invention Y relates;` TheV improved transmission llock L has-no cooperating feature in connection with cooperating actionv in connection with f the preferred to provide a clamping screw 1115 upon this arm 140, which may be clamped into engagement with the adjusting screw 144 to prevent operation of the latter except Vwhen the transmission is being operated by' authorized persons. The supporting con- .struction 138 also includes a laterally extending arm portion 150, which extends laterally from the opposite side of the bar 139 from `that which the arm portion 140 extends, and over the reverse band, including a depending apertured end adapted to receive the reverse shaft 126 therethrough, substantially as is illustrated in Figs. 1 and 12 of the drawings. c

The supporting portion 139, substantially midway of its ends is provided with a vertical lug 152, upon which the locking bar 153 is pivotally mounted intermediate its ends. The locking bar at the free end thereof is apertured, at 158 at the forward end thereof, and which apertured portion is adapted to [it within a suitable recess provided at the forward end of the supporting portion 139, so that said aperture 158 may be placed in aligning relation with the aperturefi; 159 and A160 of the supporting portion 139. A locking bolt 162 is pivotally supported, atV 163 upon the upper end of the lug 152, and this locking bolt is substantially L-shaped in formation, including a shank portion 1.6/1 which is adapted for disposition through the align- .ing apertures 158, 159 and 1GO-in order to prevent oscillation of the lock bar 153 when it is desired that the transmission should-be locked to prevent placing of the transmission in any of its speeds.

The bolt 162 is mounted so that its shank 164: may be lifted from the apertures of the supporting bar and lock har, and to this end the cable 118 which has heretofore been eX- plained in connection with the permutation or combination lock, is connected to the bolt 162; at its free end being disposed through a* through an aperture 120 in the transmission housing 125, a suitable block 170 being placed within the housing 125 about the end of the tube 119, and the free end of the tube being screw threaded whereby to receive a nut 171 thereon to hold the same in a fixed position against unauthorized detachment thereof.

The lock bar 153, supports an adjusting screw 172 thereon, in diagonally disposed transverse relation thereon, so that the foi'- ward end 173 of the screw engages against the supporting block 128, whereby upon any movement of the supporting block the lock bar will be correspondingly moved, if the lock bolt 162 permits such movement. The opposite polygonal head of the screw 172 extends in non-interfering relation with the structure of the reverse band, and it is preferred to provide a lock nut 17 5a which may clamp the adjusting screw 172 in thegdesired adjustment. It is to be noted that this adjusting screwV 172 is located forwardly of the stud 152, and rearwardly of said stud an adjusting screw 175 may be carried by the lock bar 153, the end 176 of which cooperates against the supporting block 132 of the slow speed brake band, so that any movement of the slow speed brake band support block will transmit such movement to the lock bar 153, as can be readily understood. The adj usting screw 175 is also preferably provided with a lock nut 177 to retain the same in a desired adjusted relation upon the lock bar 153.

lV ith respect to the control of the high speed shaft 135, a leverconstruction 180 may be provided for clamping upon this shaft 135, which includes the sections 181 and 182, which may be clamped with any desired construction upon the high speed shaft 135, and at its upper end lever 180 pivotally receives a connecting rod 183, which may be adjustable as vto length; the forward end of the connecting rod 183 being pivotally connected to the outer arm portion 185 of a bell crank lever 186. rlhe bell crank lever 186 is pivotaliy connected by a pin 187 to the rear end of the supporting bar 139, so that the other arm portion 188 thereof may operate, in cam like manner, aga-inst the rear projecting end 190 of the lock bar 153, and as is illustrated in Fig. 11 of the drawings. In order to ring the lock bar back into its normal relation with the apertures 158, 159 and 160 in aligning relation, it is preferred to provide a` relatively fiat spring 192, which engages the stud 152 at one end, and at its opposite end engages an upstanding portion 193 of the lock bar 153, substantially as is illustrated in Figs. 11 and 12Vof the drawings.

From the foregoing description of the transmission lock, the operation can be readily understood. If the reverse band is tightened incident to operation of the reverse band, the supporting block 128 will be moved planetary) type of transmission mechanism` adapted to be controlled conjointlytherewith, I do not mean to imply any limitation in the use of my improved lock to such type of transmission, but it may be with equal advantage applied to other types of transf Moreover, my improved mission gearing. device for locking the cover of the transmission housing conjointly with operation (and i locking) of the switch is obviously independ- Y my invention may be employed instead of the one explained, change being made as regards the construction herein disclosed, provided the means stated by any ofthe following claims or theequivalent of such means be employed.

I therefore particularly pointout and distinctly claim as my invention: I

l. In a combination lock of the class described, the combination of a casing portion, a shaft rotatable and longitudinally slidable in the casing portion, a rod longitudinally slidable in said shaft, a switch base of insulation, means connecting the switch base to said rod so that upon rotation of the rod the switch base will move therewith and be prevented from longitudinal movement when the rod is so moved in said shaft, switch contact means carried by said insulation base, and tumbler means adapted to be actuated upon rotation of said shaft.
